Hi Dan, I too have explored the Bates method and noticed some similarities between Bates and Bardon. Based on my limited experience, I've found that many aspects of the mental exercises coincide with aspects of the Bates method. For instance, Bates' idea that you can only see or think of one thing clearly at a time is similar in some respects to thought discipline: my mind is always all over the place and I find that when I am more in the present, this eases stress on my eyes and vision as well. The subtext being that this only works if you are not exerting effort; Bates talks about "voluntary" and "involuntary concentration," the former being unhealthy because it involves forcing the mind, which is counterproductive and generates tension. Overall, it seems to me from my reading and experience that the relaxing and disciplining of the mind is strongly correlated to the restoration of good vision. I don't know anything about the Hermetic view of eyesight loss per se so I'll stop there in case this wasn't where you're wanting to go with your question. David
